CIRCULAR WALL.

To LZZ 207mm t may concern.'

Be it known that l, LnoN BALABAN, a citizen or' the German Empire, and resident of 22 Niedstrasse, Berlin-F`riedenau, Germany, have invented certain new and usefulA forcing members inserted into and between said bricks or stones together with concrete which is rammed in while the bricks or stones are being walled up.

The nature of the invention consists in the features that, as regards, for instance, annular walls, chieiiy moulded bricks or stones having a key-shaped longitudinal section are used, every stone consisting of a longitudinal leg or limb and of two transversely disposed arms or limbs located at one end of said leg and extending to the same side thereof and being spaced for a certain measure. These stones are set in the bond in layers in such a manner that their longitudinal portions lie alternately at the outer and the inner side of the wall, and the end of every longitudinal portion closes the space existing between the two transverse portions of the respective adjacent stone'. The spaces form vertical channels in the superposed layers of the stones, and concrete combined with reinforcing iron members is rammed into said channels.

4 W'hen a certain number of the horizontal layers of stones has been set, a layer ot trough-shaped hollow stones is set, these stones being intended to receive a horizontal ring of reinforced concrete imbedded into the horizontal annulus formed by said trough-shaped stones.

Between the layer-joints of the longitudinal portions or legs of the l'irst-mentioned stones bow-shaped reinforcing members are arranged; these members are connected with the reinforcing members embedded in the concrete contained in the vertical channels formed by the su erposed spaces existing between the transverse portions or limbs oi' the said stones.

T he thin longitudinal members or legs of' the layers formed by the moulded stones may be covered, if desired, with 'crampshaped or clamp-shaped hollow stones forniing, together with the wallsioi said longitudinal portions or f legs, insulating airchambers, as is all more fully described hereinafter.

My invention is illustrated by way of example in thel accompanying drawing in which Figures l and 2are plans of two rows of the' main sto-nes which are to 'form ltwo superposed layers; Figure 3 is a plan of a row of layer of the troughfshaped intermediatestones also mentioned inthe preamble; Figure @isa vertical section inthe P plane I-Iof Fig. 6, the scale ybeii'ig how-` ever, that of Figs. 13; Figure'` is a vertie` cal section in the plane Il-Il of Fig 6, the.

scale being also that of Figs lf3; Figure 6 is a horizontal section in the plane Ill-HI of Fig. 5,*drawn to an enlarged scale; and Figure 7 is a plan of a layer composed of air-chamber forming auxiliary stones and of appropriately modilied main stones.

The main stones (Figs. l and 2) consist each of a longitudinal leg` a and of two transverse arms b and c which are located at and near one end oi said leg, are spaced for a certain measure, as shown, and extend both in the same direction, the configuration in plan of such a stone resembling, therefore, somewhat a key. These stones are set in such a manner that the legs c Vlie alternately at the 4outer and the `inner side or surface of the wall, and the end of an outer leg close the space existing between the arms of the adjacent inner leg, and reversely (Figs. l, 2 and 6); The horizontal y direction in the superposed layers alternates also, as appears from a comparison of Figs. l and 2, the arms b and lc being located in one layer at the right hand end of the respective stones, and in the following layer at the'leit hand end thereof. /The arms of the stones of the several layers lie always'vertically over one another and form vertical channels Z into which are inserted the rein 'lim forcing members and is lrammed the coni crete enclosing', and co-operating with, thesev members. c Fig. 6 denotes the reinforcing conc-rete cores located between the superposed arms Z2 and c of the main stones a b c.
